BLE低功耗蓝牙UTS插件接口文档

1. 蓝牙UTS插件

<script>

    //蓝牙UTS插件
    import * as BLE from "@/uni_modules/Lizii-ble-uts";

    export default {
    }

</script>

2. 设置蓝牙回调

<script>

    //蓝牙UTS插件
    import * as BLE from "@/uni_modules/Lizii-ble-uts";

    export default {

        onLoad() {

            //设置蓝牙回调
            BLE.setDeviceCallback(function(res){
                console.log(res);
                if (res.type == "onBluetoothEnable") {
                    var enable = res.data;//蓝牙打开还是关闭对回调
                } else if (res.type == "onDiscoveryDevice") {//发现蓝牙回调，需要这里选择蓝牙连接
                    var name = res.data.name;
                    var address = res.data.address;
                } else if (res.type == "onConnected") {//连接成功回调
                    //发现服务
                    BLE.discoverServices(that.address);
                } else if (res.type == "onDisconnected") {//连接断开回调

                } else if (res.type == "onConnectFailed") {//连接失败回调

                } else if (res.type == "onDiscoverServices") {//发现服务回调
                    //发现特征
                    BLE.discoverCharacteristics(that.address, that.serviceUUID);
                } else if (res.type == "onDiscoverCharacteristics") {//发现特征回调
                    //设置通知特征
                    BLE.enableNotifyValue(that.address, that.serviceUUID, that.notifyCharacteristicUUID);
                }
            });
        }
    }

</script>

3. 设置数据回调

<script>

    //蓝牙UTS插件
    import * as BLE from "@/uni_modules/Lizii-ble-uts";

    export default {

        onLoad() {

            //设置蓝牙回调
            BLE.setDeviceCallback(function(res){
                console.log(res);
            });

            //设置数据回调
            BLE.setDataCallback(function(res){
                console.log(res);
                if (res.type == "onNotifyValue") {
                    var address = res.data.address;//蓝牙地址
                    var service = res.data.service;//服务
                    var characteristic = res.data.characteristic;//特征
                    var data = res.data.data;//数据，字节的大小范围是-128～127，小于0需要加上256
                } else if (res.type == "onWriteValue") {

                } else if (res.type == "onReadValue") {

                }
            });
        }
    }

</script>

4. 初始化(必须)

<script>

    //蓝牙UTS插件
    import * as BLE from "@/uni_modules/Lizii-ble-uts";

    export default {

        onLoad() {

            //设置蓝牙回调
            BLE.setDeviceCallback(function(res){
                console.log(res);
            });

            //设置数据回调
            BLE.setDataCallback(function(res){
                console.log(res);
            });

            //初始化(必须)
            BLE.initWithOption({
                needBondWhenConnect:true,//设置设备连接之前是否需要先配对
                mtuSize:256
            });
        }
    }

</script>

5. 开始蓝牙扫描

startDiscovery() {
    //检查权限并授权
    BLE.checkPermissions(function(res){
        console.log(res);
        if (res.result == true) {
            //开始蓝牙扫描
            BLE.startDiscovery();
        }
    });
}

6. 停止蓝牙扫描

stopDiscovery() {
    //停止蓝牙扫描
    BLE.stopDiscovery();
}

7. 蓝牙连接

connect() {
    //蓝牙连接
    BLE.connect(this.address);
}

8. 断开连接

disconnect() {
    //断开连接
    BLE.disconnect(this.address);
}

9. 发现服务

//发现服务
BLE.discoverServices(that.address);

10. 发现特征

//发现特征
BLE.discoverCharacteristics(that.address, that.serviceUUID);

11. 设置通知特征

//设置通知特征
BLE.enableNotifyValue(that.address, that.serviceUUID, that.notifyCharacteristicUUID);

12. 发送数据

//发送数据
var bytes = [0x01, 0x02, 0x03, 0x04, 0x05, 0x06];//字节的大小范围是-128～127，大于127需要减去256
console.log(bytes);
BLE.writeValue(this.address, this.serviceUUID, this.writeCharacteristicUUID, bytes);
